You have downloaded the source code. apachectl is in there, but it's only in source form. You'd have to compile that and install the resulting binary.

But, unless you have a special need, don't. Instead,

yum install httpd

That will get you the compiled package, properly configured with a basic setup, and with all of the tools, including /usr/sbin/apachectl.

The version of Apache is slightly older than the one you've downloaded, but it includes backported security patches, and we're way past the era when new minor releases of Apache included very exciting new features, so it's unlikely that you really need it.
